+### `hide_dnsmasq_warn`
+
+Should FTL hide warnings coming from dnsmasq?
+
+By default, FTL reports warnings coming from the embedded dnsmasq DNS server to the
+FTL log file. These warnings can be useful to identify misconfigurations or problems
+with the DNS server. However, some warnings may be harmless and can be ignored in
+certain setups. Enabling this setting will hide all dnsmasq warnings.
